Stage Patter. I think it depends on the band, what level your playing at and where. What works in a theater or large stage festival gig might not work in a bar.
Just think about it. A signed national touring act might get more value out of cool clever patter. I always thought if your not famous going on and with some personal story is kind of weird to me. I remember some local guy starts off with this banter with something like,
" well you know when your in the public eye" and my first thought or reaction was, " but your not in the public eye" lol
On the other hand at the local level bands that don't have a member that's good with "the mouth" might come across as boring.
